I had a bit of difficulty with the game, since you can’t really tell which parts of the car can go on the horizontal roads. Also the game-over if you go on the grass seems exactly the same as the one from turning the wrong way, so that may have confused me initially as well.
(It’s a good thing I know enough about US culture to know that ‘Target’ is also a store-chain – that did make the joke work for me at least.)
